The test data are obtained similarly to the development data, except that the sources have different positions. Depending on the mixture, the source directions of arrival vary between -60 degrees and +60 degrees with a minimal spacing of 15 degrees and the distances between the sources and the center of the microphone pair vary between 80 cm and 1.20 m.

File naming convention

The test data consist of WAV audio files containing stereo mixture signals, that can be imported in Matlab using the wavread command. These files are named <srcset>_inst_mix.wav or <srcset>_<mixtype>_<spacing>_mix.wav, following the same convention as for the development data.
